A joke, a play on words of the Beatlemania phenomenon of the 1960s. Justin Bieber is a fruitbowl who should not continue to make music.

Victims of Biebermania are around the ages of 3-13 and have undeveloped breasts, haven't hit puberty, and annoying whiny voices just like their hero, Justin.
Man, why is your sister so crazy?
She's got Biebermania, bro.
